Protein Misfolding
Protein misfolding is a phenomenon in which proteins within an organism fail to properly fold into their native conformation. This can lead to the formation of stable aggregates or amyloid fibrils that are often linked with diseases such as Alzheimer's, Huntington’s and Parkinson's. Emerging studies are indicating that protein misfolding is one of the key issues that prevents the advancement of biotherapeutics and intractable drugs. This misfolding could result from many factors, including mutations in the protein-coding gene, changes in environmental conditions or abnormal interactions with other biomolecules. Advancement in chemistry has led to the development of various approaches and techniques to understand and combat protein misfolding. Among these are formulation optimization, protein engineering, and screening methodologies utilized to isolate compounds that interact with the protein of interest. Formulation optimization involves modification of environmental variables including pH, buffer solution, ionic strength and temperature to influence protein stability. Protein engineering technology allows for tailored selection and modification of amino acid residues to fold the protein in the correct configuration. Screening methodologies on the other hand, allow identification of molecules that can prevent or reverse protein misfolding. Such molecules, often referred to as chaperones, can be used as treatment options by targeting the early stages of protein misfolding diseases, thus slowing or halting the progression of these diseases. In summary, protein misfolding is a current area of research, and approaches such as formulation optimization, protein engineering, and screening methodologies hold potential in mitigating the effects of an array of protein misfolding disorders.
